Tetrahydrofuranyikhompawundi yeekhemikhali kunye ne-molecular formula C4H8O. Lulwelo olungenambala, olunokutsha kunye nevumba elimnandi elithozamisayo. Le mveliso sisinyibilikisi esiqhelekileyo kumashishini ahlukeneyo, kubandakanywa amayeza, iiplastiki, kunye nemveliso yepolymer. Nangona inobungozi obunokuthi bube khona, ngokubanzi, iTetrahydrofuran ayiyona imveliso eyingozi.
Umngcipheko omnye onokubakho weTetrahydrofurankukutsha kwayo. Ulwelo lunokukhanya kwe--14°C kwaye luyakwazi ukuvutha lula ukuba ludibana nentlantsi, ilangatye okanye ubushushu. Nangona kunjalo, lo mngcipheko unokulawulwa ngokulandela ukugcinwa okukhuselekileyo kunye neenkqubo zokuphatha. Ukunciphisa ingozi yomlilo kunye nokudubula, kubalulekile ukugcina imveliso kude nemithombo yokutshisa kunye nokusebenzisa umoya ofanelekileyo.
Enye ingozi enokwenzeka yeTetrahydrofurankukukwazi ukubangela ukucaphuka kwesikhumba kunye nokutsha kweekhemikhali. Xa ulwelo ludibana ngqo nolusu, lunokubangela ukucaphuka, ububomvu, nokudumba. Lo mngcipheko unokuncitshiswa ngokunxiba iimpahla ezifanelekileyo kunye nezixhobo zokukhusela ngelixa uphethe imveliso. Iiglavu, iiglavu, kunye nempahla yokukhusela inokuthintela ukuvela kwesikhumba.
Tetrahydrofuranikwalulwelo oluguquguqukayo, okuthetha ukuba lunokumka lula kwaye luveze ingozi yokuphefumla. Ukuboniswa ixesha elide kwimiphunga kunokukhokelela kwisiyezi, intloko ebuhlungu, kunye neengxaki zokuphefumla. Nangona kunjalo, lo mngcipheko unokuphetshwa ngokusebenzisa imveliso kwindawo engenamoya kwaye uthintele ukuvela ixesha elide.
Ngaphandle kwezi zingozi ezinokubakho, iTetrahydrofuran yimveliso eluncedo kakhulu. Ngokuqhelekileyo isetyenziswe kwishishini lamachiza njenge-solvent yezithako ezisebenzayo. Kwakhona i-solvent enexabiso ekuveliseni iipolymers kunye neeplastiki, apho ivumela ulawulo oluchanekileyo kwiimeko zokucubungula kunye neempawu zokugqibela zemveliso.
Ngaphezu koko, le mveliso kulula ukuyiphatha kwaye inetyhefu ephantsi. Kuye kwaboniswa ukuba namanqanaba aphantsi etyhefu kwizifundo kwizilwanyana, okwenza kube kukhuselekile ukusetyenziswa kwiinkqubo zokuvelisa ezilawulwayo. Le mveliso kwakhona biodegradable, nto leyo ethetha ukuba yophuka ngokwendalo izinto ezingenabungozi ekuhambeni kwexesha.
Ukuqukumbela, ngelixa kukho imingcipheko ehambelana nayoTetrahydrofuran, le mingcipheko inokulawulwa ngokulandela iindlela zokuphatha nokugcina ngokukhuselekileyo. Ngokusetyenziswa kwayo ngokubanzi kumashishini ahlukeneyo kunye netyhefu ephantsi, iTetrahydrofuran yimveliso ekhuselekileyo nexabisekileyo edlala indima ebalulekileyo kwiinkqubo zokuvelisa zanamhlanje. Ngethuba nje isetyenziswe ngokuchanekileyo, akukho sizathu sokucinga ukuba yimveliso eyingozi.
